Altered microRNA profiles in cumulus cells isolated from PCOS patients

Project description:To identify the altered miRNA expression profiles of PCOS patients, the differentially expressed miRNAs were identified from cumulus cells of PCOS patients by comparing to that of normal women. Case-control study that involved 18 women with PCOS and 18 women without PCOS (control). The miRNA expression profiles of cumulus cells were identified by miRNA array.

LncRNAs expression signatures of cumulus cells isolated from PCOS patients revealed by microarray

Project description:Our study is the first one to determine genome-wide lncRNAs expression patterns in cumulus cells of PCOS patients by microarray. The results displayed that clusters of lncRNAs (n=623) were aberrantly expressed in PCOS patients compared with non-PCOS patients. Many differentially expressed lncRNAs were transcribed from regions on chromosome 2 and classified into enhancer-like lncRNA subgroup. XLOC_011402 (PWRN2) was found for the first time that it was not only expressed in testis but also in cumulus cells. All the results revealed that lncRNAs differentially expressed in cumulus cells may exert a partial or key role in hormone abnormalities of PCOS patients and maybe impact on oocyte development. Taken together, this study may provide potential targets for further treatment of PCOS and novel insights into oocyte development.

Gene expression microarray profiles of cumulus cells in lean and overweight-obese polycystic ovary syndrome patients

Project description:Objective: The etiology of PCOS is mostly unknown. Existing data support both genetic and environmental factors in its pathogenesis. Design: Prospective case - control study. Setting: University Hospital. Patients: 25 patients undergoing IVF-ICSI treatment. Intervention: Genome-wide oligonucleotide microarray technology was used to study differential gene-expression patterns of cultured human cumulus cells from IVF patients divided into 4 groups according to disease state (PCOS vs. Control) and BMI (Obese vs. Lean). Results: Two differential PCOS gene expression profiles were established: Lean-Type was formed by comparing PCOS lean (PL) vs. non-PCOS lean (NL) individuals; Obese-Type was formed by comparing PCOS obese (PO) vs. non-PCOS (NO) obese patients. Conclusions: Different molecular pathways are associated with PCOS in Lean and Obese individuals, as demonstrated by gene expression profiling of cumulus cells. Our findings provide insights into the molecular pathogenesis of PCOS. We used microarrays to study the gene expression of human cultured cumulus cells. We compared the genes expression of lean PCOS, Obese PCOS, lean controls and obese controls. Different molecular pathways are associated with PCOS in Lean and Obese patients. Keywords: disease state analysis

Expression data from human cumulus cells isolated from oocytes at MI and MII stages in polycystic ovary syndrome (PCOS) patients

Project description:Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder that is characterized by increased circulating androgen levels, anovulatory infertility, and frequently, insulin resistance and hyperinsulinemia.The abnormity of oocyte nuclear maturity is the main reason for anovulatory infertility and pregnancy loss in PCOS patients.The bidirectional exchanges between oocyte and contiguous CCs are important for oocyte competence acquisition, early embryonic development and CC expansion.Gene expression profiles of CCs has been suggested to predict embryo development and pregnancy outcome. We used microarrays to detail the global programme of gene expression of CCs isolated from oocytes at metaphase I (CCMI) and metaphase II (CCMII) stage under controlled ovarian stimulation (COS) cycle in PCOS patients. Cumulus cells were isolated from oocyte at stage metaphase 1(MI)and stage metaphase II (MII) of PCOS patients for RNA extraction and hybridization on Affymetrix microarrays. For microarray analysis, we used three chips for each CC category. That is, CCMI1,CCMI2,CCMI3,CCMII1,CCMII2 and CCMII3.

To compare the transcriptome expression of cumulus granulosa cells between PCOS patients with insulin resistance and women undergoing assisted reproduction for fallopian tube reasons

Project description:Purpose polycystic ovary syndrome (PCOS) is the most common endocrine and metabolic disorder in women of childbearing age. It is characterized by follicular dysplasia and hyperandrogenemia. Insulin resistance plays an important role in the development of PCOS.However, the mechanism of regulation and interaction between insulin resistance and follicle development remains unclear.The aim of this study was to identify differential genes associated with follicle development in cumulus granulosa cells in PCOS patients with insulin resistance compared with controls. Methods In this study, RNA-seq, bioinformatics analysis and reverse transcription qPCR (RT-qPCR) were used to analyze the gene expression in cumulus granulosa cells.A total of seven cDNA libraries were constructed from three PCOS samples and four control samples.3 μg of RNA was used as starting material for each sample.Ribosomal RNA was removed using the Epicentre rigo-zero ™ Gold Kit (Epicentre, Illumina, Madison, WI, USA). Results Compared with the control group, there were 2233 DEGs in the PCOS group, including 1158 up-regulated genes and 1075 down-regulated genes. Some different expression patterns were observed in the two groups.The next series of experiments verified the effect of some genes on oocyte development. Conclusion Our study showed that the differential expression of transcriptome in cumulus granulosa cells could affect the growth, development and maturation of oocytes.Meanwhile, the results of RT-PCR and Elisa showed that the expression of renin angiotensin system was changed in PCOS patients with insulin resistance, and these changes could affect oocyte maturation and excretion through cumulus granulosa cells.
